Greetings and thanks in advance for any help. I've installed newly purchased Photoshop CS5 on my relatively new (4 months old) Macbook Pro computer. I've uninstalled/reinstalled 3 or 4 times; same results each time. What happens is I can open the program once normally, right after install, and begin to work on a new project. Shortly thereafter it crashes, and from then on I cannot use the software unless I hold down shift-option-cmd to delete the preferences file, every time I open it. If I don't delete the preferences file, the software will open but nothing in it works. Everything is non-responsive or acts weirdly, until I hit certain buttons which just causes it to crash. As long as I've deleted the preferences file when starting it, all is well. If I don't do that, I can't use the software.

Does anyone know what might be happening or can you suggest a fix? I can provide error logs and such but don't know where any of that is; I'm a new convert to MAC. Thanks again for any help.

Thanks so much for chiming in. I checked all the fonts using Fontbook and they all check out alright. I don't know how to check video cards and drivers. I also don't know what you mean by "something I brought over from my other system". I'm using a new install of CS5 on a new MAC.

Also, can you tell me where to find the crash reports on a MAC? I'd love to find it and provide it if so. Thanks so much!
